This physics video tutorial provides a basic introduction into the venturi meter and how it works. It's a device used to measure the velocity of a fluid in a tube. It works by changing the cross - sectional area of the pipe to cause an increase in fluid speed which leads to a reduction of pressure which can be visually measured due to the height difference in the two columns. This video explains how to derive the formula that can be used to calculate the fluid's velocity on the left side of the meter using bernoulli's equation. The flow speed in the throat can be calculated using the equation of continuity and the difference in water pressure can be calculated using the gauge pressure formula for fluids or using bernoulli's principle. This fluid mechanics video contains all the formulas and equations you need when dealing with physics problems involving the venturi effect.
